Overview
The SN74LVC2G125DCTR is a dual bus buffer gate designed by Texas Instruments, operating within a wide voltage range of 1.65 V to 5.5 V. This device features dual line drivers with 3-state outputs, making it versatile for various applications. The outputs are disabled when the associated output-enable (OE) input is high, and the device supports partial-power-down applications using the Ioff circuitry, which prevents damaging current backflow when the device is powered down. The SN74LVC2G125DCTR is available in several package options, including SSOP, VSSOP, and DSBGA, and utilizes Texas Instruments' NanoFree™ package technology, which is a significant breakthrough in IC packaging concepts.
